Hello,i have at the moment sli gts 250s and a pair of gts 450s which i just bought on a shopping spree, im wondering is there any point in keeping the 450s as the 250s seem to be pretty good together , its just that the 450s cost alot more and i could do with getting my money back if the 250s are just as good . any help would be great . i will also run benchmarks on both sli configs and post later : )
